The underwater shot was done with my S95 in a RecSea underwater housing while freediving. The Sea anemone and clownfish were at a relatively shallow depth so ambient light + PP was more than enough to bring out the colors. These little buggers are extremely active moving around like crazy, so it's a matter of taking a lot of pictures and hopefully getting them in a good position over the anemone. I should have used a little higher arpeture on that shot because the clownfish on the lower right is a bit out of focus - oh well
